Three months after Intel has released their new technology, laptops based on the Centrino(TM) features are already very popular in the Linux community. For almost all Centrino based laptops from different manufacturers there are installation reports available.
But the "Intel Support of Centrino Under Linux Petition" states "currently support is quite lacking and only half of the technology has any form of drivers. Intel has flipped on the issue of Linux. When Centrino was introduced they reported that Linux would indeed be supported. Now, after conversing with them, they have said that they have no plans at all to support Linux with respect to Centrino any more than they have." 
Please support the petition.
